Costs of aqueducts



How the construction of aqueducts was financed?
Some remarks in advance:
  • Money could be furnished by public (treasury, town council) or by privati (owner, maecenas) sources
  • Note that it was not always clear whether the money was used for construction work only (in part or total) and / or for maintenance or operation.
  • Note that sometimes extra financial resources were available: war booties. The construction of the Aqua Anio Vetus was financed by the victory over Pyrrhus (Frontinus 6). The construction of the Aqua Marcia could have been paid by the victory over Carthage (146 BC)
  • And please realize that the given examples stems from quite different time periods and are not always comparable because of inflation.
